Description

GM Power Folding Mirror Repair Kit (Billet Steel)

Stop replacing $1,000 mirrors with the same flawed parts. The factory power-folding mirrors on GM trucks and SUVs fail because of a single, inexpensive plastic gear. When that gear cracks, dealers charge upwards of $700–$1,200 for a full mirror assembly that carries the exact same defect.

GruvenParts.com provides a permanent, engineered solution: high-strength Billet Steel gears and high-torque motors designed to outlast the vehicle.

The Engineering Gap: OEM Failure vs. GruvenParts Solution

Feature

 

OEM Factory Unit / Boost Auto

 

GruvenParts Billet Solution

Gear Material

 

Thin, fragile plastic spur gear.

 

High-strength Billet Steel (integral spiral shaft).

Failure Mode

 

Fatigue cracking from age or minor impact.

 

Virtually indestructible; tested to 5,000+ cycles.

Motor Specs

 

Low-torque; prone to burnout.

 

High-torque custom motor for smooth operation.

Grounding

 

Externally grounded (Incompatible with metal).

 

Internally grounded to prevent BCM short circuits.

Cost

 

$700 - $1,200 (Full assembly).

 

Under $100 (DIY Gear/Motor Kit).

Critical Technical Note: Why the Motor Matters

You cannot simply install a metal gear onto the factory GM motor. The OEM motor circuit is not designed for a conductive metal gear; attempting to "mix and match" will short out your Body Control Module (BCM). Every GruvenParts kit includes our custom-engineered, internally grounded motor to ensure electrical safety and increased torque.

Choosing Your Repair Path

Path 1: DIY Gear & Motor Kit The most cost-effective choice for those comfortable with a workbench repair.

  • Includes: 1 or 2 Billet Steel Gears and High-Torque Motors.
  • Best For: Owners looking for a permanent fix at the lowest price point.
  • Compatibility: Fits 2007–Present GM Non-Tow Mirrors (Silverado, Sierra, Tahoe, Yukon, Suburban, Acadia, Traverse, Enclave, Escalade).

Path 2: Pre-Assembled Drive Unit (Core Exchange)

Skip the internal assembly and swap the entire drive unit.

  • Includes: A fully rebuilt motor drive unit with the steel gear and motor already installed and tested.
  • Process: Requires a $30 core deposit. Send us your rebuildable old unit to receive your refund.
  • Note: Due to high demand and core availability, lead times can vary (approx. 4–6 weeks). For the fastest turnaround, you may send your unit in for a same-day rebuild.

This kit is designed for Standard (Non-Towing) Power Folding Mirrors on the following 2007–Present models:

  • Chevy: Silverado, Tahoe, Suburban, Avalanche, Traverse.

Expert Installation Tips & FAQ

To ensure a successful repair and protect your vehicle's electronics, please review these critical requirements before beginning your installation:

  • The "No-Mix" Rule (Electrical Safety): Never attempt to install the Billet Steel gear using the original OEM motor. The factory motor is externally grounded; using it with a metal gear will create a short circuit and permanently damage your Body Control Module (BCM). You must use the internally grounded motor provided in our kits.
  • Mirror Type Verification: These parts are specifically engineered for Standard (Non-Tow) Mirrors. If your mirror extends outward for towing, these gears will not fit. Click here for our Towing Mirror Gear Page.
  • 2014+ Pickup Differences: If you own a 2014 or newer Silverado/Sierra, the mirror frame plastics differ from earlier generations. While the internal drive unit is identical, the housing disassembly requires a slightly different approach. Please refer specifically to our 2014-2018 PDF Guide.
  • The "Core" Condition (Option 2): If purchasing the pre-assembled drive unit, your returned "core" must be in rebuildable condition. We can only accept units where the motor or spur gear is the point of failure. If the main plastic housing or frame of your drive unit is physically shattered, it cannot be rebuilt or refunded.
  • Tool Tip: We recommend having a basic set of trim removal tools and a small socket set. Take photos during disassembly to ensure wire routing remains clear for the re-install.

    Works better than NEW!

    Posted by Ted on 7th Sep 2019

    2009 Chevy Silverado LTZ driver's mirros stopped folding months ago, then passenger mirror failed recently. Thanx to Silverado Forum for leading me to this repair kit versus buying new mirrors for > $400+ dollars!!! I purchased the new motors and gears. 25 pages of instructions is a lot for a DIY project, but being an engineer and former manufacturing technician I gave it a shot. Directions were almost as thorough as DoD drawings and specs I was familiar with. The MOST DIFFICULT part of the job is removing and re-installing the retaining clip and large spring assy. I purchased a 3/4" PVC tee and used a vice to hold the assy. took a little effort but it worked!! Mirror folds better and faster than before!

    Parts worked like a champ!

    Posted by Unknown on 7th Sep 2019

    I ordered the pre-attached gear and motor kit for a 2010 Chevrolet Silverado passenger side mirror. The mirror has the turn signal, heat, and the auto folding mechanism... needles to say, there are a lot of wires. The parts arrived on time and the step by step instructions on the Gruven parts website was exactly on point and helped out a lot. I am not a gear head by any means, and I was able to complete this project. The tension spring definitely needs to be compressed with a press and deep well socket. That seemed to work the best. These are definitely the parts you want to replace that broken plastic gear.

    work perfect

    Not to hard to do, came up with my own trick for removing that spring retainer, use a faucet socket set. They are perfect for this was able to do it and control the retainer so I didnt go flying, havent seen anybody else do this yet, it's really the best way in my opinion. They are sheet metal "sockets" typically found in the plumbing section at a hardware store. They are meant to tighten the big nut under the sink that holds the faucet down. They are absolutely easy to use for this.

    Works great!

    Posted by Bryan on 7th Sep 2019

    So far so good. The power folding mirror motor unit works great and seems smoother than factory. It’s a bit faster and louder than factory but it functions well. The finish could have used some help though which is the main reason I only gave it four stars. The unit I received was a bit weathered, beat up, and the snap clasps were not refastened. Works great though and you can’t see the unit once it’s installed. The 3 factory pins hold everything thing in place so I’m not too concerned about the snap fittings but it did surprise me for a $270 unit. I will definitely order the passenger side unit from Gruven once my factory unit goes out and thinking of ordering a full set for my other Escalade. Sounds like that will be soon.

    folding mirror's Not

    Posted by Larry Kraszewski on 6th Sep 2019

    Purchased gear and motor kit for both sides one was broken did both, the repair was very simple and straightforward. I purchased the gears already installed as did not have time to have vehicle down that is good option. Mirrors work great a little faster folding time I think filing the detent did that all and all great product.

    Top Shelf Quality!

    Posted by Scott K on 5th Sep 2019

    Passenger mirror gave up so looking for a replacement when I read a forum mentioning this great solution and to save money as well! Thankfully I bought the set of 2 premounted with motors because my driver side mirror was on its way out when I found the plastic gear already cracked when I inspected it. Thanks GruvenParts!

    Fit works perfectly

    Posted by Randy Redmond on 28th Aug 2019

    Ordered the gear/motor to repair my passenger mirror that suddenly stopped folding in. The parts fit and work perfectly. My only issue is, the parts work to well! I should have ordered parts to do both mirrors. The passenger side once I had it done worked so smooth and a lot faster than the drivers. I have ordered the set for the other mirror. Shipping was fast. Very nice company to contact and deal with. Highly recommend.
